Belfast is a county of red-brick Victorian terraces and generous interwar suburban housing. That is exactly the kind of building stock a sash window restoration has to be drawn around, so we allow for it at survey stage rather than on fitting day — walls get checked for wind and plumb, floors for level, and the setting-out is taken from the worst reading, not the best.
How we approach it
Off-the-shelf units are made to standard sizes and then filled out with scribe strips. Our sash window restoration work is cut to the dimensions taken from your Belfast property, so there is no packing, no filler and no gap that opens up in year two.
How we build it
Carcass work is birch ply or MR MDF depending on span and load. Face frames and doors are solid hardwood. Everything is machined on the same setting so stiles, rails and reveals line through, and shadow gaps stay parallel from one end of the run to the other.
Finish and materials
Every finished job gets a short handover: what the surface is, how to clean it, and how to adjust a hinge if a door drops after the heating has been on for a season. Adjustment is normal in timber and takes about two minutes once you know which screw to turn.

Straight answers
Sash Window Restoration in Belfast — common questions
Can you save the original glass?
Yes, and it is worth saving. Old cylinder and crown glass has a movement and a slight distortion that no modern glass reproduces. We de-glaze carefully, keep it aside and re-putty on reassembly.
Can double glazing be retrofitted into original sashes?
Sometimes. The rebate has to be deep enough to take a slim unit, and the sash has to be strong enough for the extra weight. Where it is not viable, secondary glazing or a high-performance draught-proofing overhaul gets much of the benefit.
How long does restoration take per window?
One to two days per window on site for an overhaul. If sashes need to go back to the workshop for splicing, allow two to three weeks and we fit temporary boarding or a holding sash.
Is it worth restoring rather than replacing?
If the boxes and pulley stiles are sound, almost always. Restoration keeps the original glass and joinery, is cheaper, and in a conservation area or listed building it is frequently the only option that will be approved.
Do I need to empty the room before you fit?
Clear the working wall and anything fragile. We bring dust sheets and a vacuum-extracted saw, but fitting makes dust and we would rather your furniture was out of the way. For kitchens we will agree a sequence with you so you keep a sink and a kettle for as long as possible.
